Answer:
The boat's velocity relative to Earth is 3.91 m/s.
Explanation:
Given;
speed of ferry due north, 
= 2.5 m/s
speed of the river to the east, 
= 3.0 m/s
The boat's velocity relative to Earth is given by;
Therefore, the boat's velocity relative to Earth is 3.91 m/s.
If Equal distance is traveled in equal interval of time then it is known as uniform motion in which velocity of object will remain same.
Then if distance covered will be same and the time taken to cover same distance is decreasing then it shows that speed is increasing with time due to which it took less time to cover same distance. This is also known as positive acceleration.
Now if the distance covered will be same and time taken to cover same distance is increasing then it shows that speed is decreasing with time due to which it took more time to cover the same distance. This is also known as negative acceleration.
Now in the above case it is given that the first mile takes you 10 minutes. The second mile takes you 20 minutes. So the time taken is increasing while we cover same distance so this is an example of <u>Negative Acceleration</u>
Answer:
55.128kg
Explanation:
P= m×v
or, m=P/v = 430/7.8 = 55.128 kg
Answer:
There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its
A sand castle that was changed by the ocean waves would be slowly taken away from by the waves and would just become a smooth mound of sand. If Dylan stomped on it then it would still have all of the same sand as before but in a different shape. It would also become a mound of sand but it would have all the same sand as before.
(I don't know if I was supposed to talk about fancy physics stuff so I just gave a basic explanation. I don't know if my answer is really right or not... hope it helped though :))
